Logic Pro? about "file not found result code = -43"

When I go to the media tab and select Jam Pack Rhythm Section, then select one of the instruments, it always works, but then if I select another instrument, it gives me this error code:

file not found result code = -43

If I select the same file that just gave me the error (but make it my first selection) then it works. But then whatever I select after that...it gives me the error.

Can anyone help with this?
